4-(4-Bromophenyl)-3-methyl-1-phenyl-6,7-dihydro-1H-pyrazolo[3,4-b]thieno[2,3-e]pyridine 5,5-dioxide

Abstract

In the title compound, C21H16BrN3O2S, the pyrazole and pyridine rings are nearly coplanar, the dihedral angle between their planes being 3.17 (14)°. The 2,3-dihydro­thio­phene ring adopts an envelope conformation. The 4-bromo­phen­yl/pyridine ring and phen­yl/pyrazole rings form dihedral angles of 60.06 (9) and 33.49 (11)°, respectively. There is an intra­molecular C—H⋯N hydrogen bond. The crystal packing is stabilized by inter­molecular C—H⋯O hydrogen bonding and C—H⋯π inter­actions.
